STMicroelectronics’ New Sub-Dollar STM32F3 Floating-Point Digital Signal Controllers Now Ready to Order from Distributor Stock

Geneva

STMicroelectronics has announced that its new STM32F301/302/303 microcontrollers based on the ARM® Cortex®-M4 core with Floating-Point Unit (FPU) are in full production and now in stock at distributors, available immediately to deliver outstanding performance and system-on-chip integration for value-conscious advanced applications.

The market-first sub-dollar Cortex-M4 devices with FPU in volume production, the new STM32F301 access product line brings 32KBytes to 64KBytes on-chip Flash and 16KByte of SRAM, offering an easy step into ARM Cortex -M4-core-based MCU development. The STM32F302 and STM32F303 offer extended Flash density from 32KBytes to 256KBytes. Additional STM32F3 devices with up to 512KBytes of Flash will be introduced later this year.

STM32F3 devices combine the 72MHz ARM Cortex-M4 core featuring DSP instruction set and FPU with high-performance analog peripherals to bring advanced integration to entry-level mixed-signal control applications. The full compatibility with the STM32F0 series gives customers the strong advantage of a single development platform. STM32F303 offers higher performance (90DMIPS) thanks to its Core-Coupled Memory (CCM-SRAM), which provides a “routine boost” equivalent to >100MHz CPU frequency execution from Flash.

The new sub-30ns analog comparators combined with 5Msample/s 12-bit ADC, the fastest ADC in any ARM Cortex-based MCU, offer ultra-fast reaction time for control-sensitive applications such as digital power, sonar, motor control, lighting, or wireless chargers. This ultra-fast ADC, with support of oversampling to allow 16-bit resolution at 20ksamples/s and 18-bit at 1.2ksamples/s, enhances precision, making these devices ideal for applications such as sensor data processing, healthcare, power meters, and instrumentation. In the new STM32F302/303 devices, the USB-LPM (Link Power Management) mode reduces connectivity power consumption.

The new mbed-compatible STM32F302 Nucleo board, available at $10.32 (NUCLEO-F302R8), joins the enablement ecosystem alongside the existing STM32F303 Discovery kit (STM32F3DISCOVERY), to help engineers try out new ideas and quickly create prototypes.

Prices for the new STM32F3 devices start at $0.89 for the STM32F301K6U6 (72MHz Cortex-M4 plus FPU) with 32KByte Flash and 16KB of SRAM in 32-pin package, for orders of 10000 pieces.
